2013-10-07ipv6: Allow the MTU of ipip6 tunnel to be set below 1280Oussama Ghorbel
The (inner) MTU of a ipip6 (IPv4-in-IPv6) tunnel cannot be set below 1280, which is the minimum MTU in IPv6. However, there should be no IPv6 on the tunnel interface at all, so the IPv6 rules should not apply. More info at https://bugzilla.kernel.org/show_bug.cgi?id=15530 This patch allows to check the minimum MTU for ipv6 tunnel according to these rules: -In case the tunnel is configured with ipip6 mode the minimum MTU is 68. -In case the tunnel is configured with ip6ip6 or any mode the minimum MTU is 1280.

2013-10-04sfc: Add PM and RXDP drop counters to ethtool statsEdward Cree
Recognise the new Packet Memory and RX Data Path counters. The following counters are added: rx_pm_{trunc,discard}_bb_overflow - burst buffer overflowed. This should not occur if BB correctly configured. rx_pm_{trunc,discard}_vfifo_full - not enough space in packet memory. May indicate RX performance problems. rx_pm_{trunc,discard}_qbb - dropped by 802.1Qbb early discard mechanism. Since Qbb is not supported at present, this should not occur. rx_pm_discard_mapping - 802.1p priority configured to be dropped. This should not occur in normal operation. rx_dp_q_disabled_packets - packet was to be delivered to a queue but queue is disabled. May indicate misconfiguration by the driver. rx_dp_di_dropped_packets - parser-dispatcher indicated that a packet should be dropped. rx_dp_streaming_packets - packet was sent to the RXDP streaming bus, ie. a filter directed the packet to the MCPU. rx_dp_emerg_{fetch,wait} - RX datapath had to wait for descriptors to be loaded. Indicates performance problems but not drops. These are only provided if the MC firmware has the PM_AND_RXDP_COUNTERS capability. Otherwise, mask them out.

2013-10-04sfc: Refactor EF10 stat mask code to allow for more conditional statsEdward Cree
Previously, efx_ef10_stat_mask returned a static const unsigned long[], which meant that each possible mask had to be declared statically with STAT_MASK_BITMAP. Since adding a condition would double the size of the decision tree, we now create the bitmask dynamically. To do this, we have two functions efx_ef10_raw_stat_mask, which returns a u64, and efx_ef10_get_stat_mask, which fills in an unsigned long * argument.

2013-10-04tcp: do not forget FIN in tcp_shifted_skb()Eric Dumazet
Yuchung found following problem : There are bugs in the SACK processing code, merging part in tcp_shift_skb_data(), that incorrectly resets or ignores the sacked skbs FIN flag. When a receiver first SACK the FIN sequence, and later throw away ofo queue (e.g., sack-reneging), the sender will stop retransmitting the FIN flag, and hangs forever. Following packetdrill test can be used to reproduce the bug. $ cat sack-merge-bug.pkt `sysctl -q net.ipv4.tcp_fack=0` // Establish a connection and send 10 MSS. 0.000 socket(..., SOCK_STREAM, IPPROTO_TCP) = 3 +.000 setsockopt(3, SOL_SOCKET, SO_REUSEADDR, [1], 4) = 0 +.000 bind(3, ..., ...) = 0 +.000 listen(3, 1) = 0 +.050 < S 0:0(0) win 32792 <mss 1000,sackOK,nop,nop,nop,wscale 7> +.000 > S. 0:0(0) ack 1 <mss 1460,nop,nop,sackOK,nop,wscale 6> +.001 < . 1:1(0) ack 1 win 1024 +.000 accept(3, ..., ...) = 4 +.100 write(4, ..., 12000) = 12000 +.000 shutdown(4, SHUT_WR) = 0 +.000 > . 1:10001(10000) ack 1 +.050 < . 1:1(0) ack 2001 win 257 +.000 > FP. 10001:12001(2000) ack 1 +.050 < . 1:1(0) ack 2001 win 257 <sack 10001:11001,nop,nop> +.050 < . 1:1(0) ack 2001 win 257 <sack 10001:12002,nop,nop> // SACK reneg +.050 < . 1:1(0) ack 12001 win 257 +0 %{ print "unacked: ",tcpi_unacked }% +5 %{ print "" }% First, a typo inverted left/right of one OR operation, then code forgot to advance end_seq if the merged skb carried FIN.

git://git.kernel.org/pub/scm/linux/kernel/git/pablo/nf-next Pablo Neira Ayuso says: ==================== The following patchset contains Netfilter updates for your net-next tree, mostly ipset improvements and enhancements features, they are: * Don't call ip_nest_end needlessly in the error path from me, suggested by Pablo Neira Ayuso, from Jozsef Kadlecsik. * Fixed sparse warnings about shadowed variable and missing rcu annotation and fix of "may be used uninitialized" warnings, also from Jozsef. * Renamed simple macro names to avoid namespace issues, reported by David Laight, again from Jozsef. * Use fix sized type for timeout in the extension part, and cosmetic ordering of matches and targets separatedly in xt_set.c, from Jozsef. * Support package fragments for IPv4 protos without ports from Anders K. Pedersen. For example this allows a hash:ip,port ipset containing the entry 192.168.0.1,gre:0 to match all package fragments for PPTP VPN tunnels to/from the host. Without this patch only the first package fragment (with fragment offset 0) was matched. * Introduced a new operation to get both setname and family, from Jozsef. ip[6]tables set match and SET target need to know the family of the set in order to reject adding rules which refer to a set with a non-mathcing family. Currently such rules are silently accepted and then ignored instead of generating an error message to the user. * Reworked extensions support in ipset types from Jozsef. The approach of defining structures with all variations is not manageable as the number of extensions grows. Therefore a blob for the extensions is introduced, somewhat similar to conntrack. The support of extensions which need a per data destroy function is added as well. * When an element timed out in a list:set type of set, the garbage collector skipped the checking of the next element. So the purging was delayed to the next run of the gc, fixed by Jozsef. * A small Kconfig fix: NETFILTER_NETLINK cannot be selected and ipset requires it. * hash:net,net type from Oliver Smith. The type provides the ability to store pairs of subnets in a set. * Comment for ipset entries from Oliver Smith. This makes possible to annotate entries in a set with comments, for example: ipset n foo hash:net,net comment ipset a foo 10.0.0.0/21,192.168.1.0/24 comment "office nets A and B" * Fix of hash types resizing with comment extension from Jozsef. * Fix of new extensions for list:set type when an element is added into a slot from where another element was pushed away from Jozsef. * Introduction of a common function for the listing of the element extensions from Jozsef. * Net namespace support for ipset from Vitaly Lavrov. * hash:net,port,net type from Oliver Smith, which makes possible to store the triples of two subnets and a protocol, port pair in a set. * Get xt_TCPMSS working with net namespace, by Gao feng. * Use the proper net netnamespace to allocate skbs, also by Gao feng. * A couple of cleanups for the conntrack SIP helper, by Holger Eitzenberger. * Extend cttimeout to allow setting default conntrack timeouts via nfnetlink, so we can get rid of all our sysctl/proc interfaces in the future for timeout tuning, from me. ==================== Signed-off-by: David S.

2013-10-03tcp: shrink tcp6_timewait_sock by one cache lineEric Dumazet
While working on tcp listener refactoring, I found that it would really make things easier if sock_common could include the IPv6 addresses needed in the lookups, instead of doing very complex games to get their values (depending on sock being SYN_RECV, ESTABLISHED, TIME_WAIT) For this to happen, I need to be sure that tcp6_timewait_sock and tcp_timewait_sock consume same number of cache lines. This is possible if we only use 32bits for tw_ttd, as we remove one 32bit hole in inet_timewait_sock inet_tw_time_stamp() is defined and used, even if its current implementation looks like tcp_time_stamp : We might need finer resolution for tcp_time_stamp in the future. Before patch : sizeof(struct tcp6_timewait_sock) = 0xc8 After patch : sizeof(struct tcp6_timewait_sock) = 0xc0 Signed-off-by: Eric Dumazet <edumazet@google.com> Signed-off-by: David S.

2013-10-03atl1e: enable support for NETIF_F_RXALL and NETIF_F_RXCRC featuresAndrea Merello
This patch allows (optionally, via ethtool) the atl1e NIC to: - Receive bad frames (runt, bad-fcs, etc..) - Receive full frames without stripping the FCS. This has been tested on my board by injecting runt and bad-fcs frames with a FPGA-based device. The particular scenario of receiving very short frames (<4 bytes) without passing FCS to the upper layer has been also tested: This could be potentially dangerous because the driver performs a 4 byte subtraction on the frame length, but I finally have NOT added anything to avoid this because it seems the NIC always discards frames so much short.. If someone still have some reason to worry about this, please tell me.. I will add an explicit SW check.. Signed-off-by: Andrea Merello <andrea.merello@gmail.com> Signed-off-by: David S.

2013-10-03brcmfmac: fix sparse error 'bad constant expression'Arend van Spriel
The definition of BRCMF_EVENTING_MASK_LEN results in a sparse error message .../fweh.c:331:22: error: bad constant expression .../fweh.c:388:22: error: bad constant expression .../dhd_common.c:256:22: error: bad constant expression This is caused by the use of roundup() in BRCMF_EVENTING_MASK_LEN and it is used to allocate an array variable on the stack. Better use DIV_ROUND_UP() macro.

2013-10-03Merge branch 'bond_hash'David S. Miller
Nikolay Aleksandrov says: ==================== This is a complete remake of my old patch that modified the bonding hash functions to use skb_flow_dissect which was suggested by Eric Dumazet. This time around I've left the old modes although using a new hash function again suggested by Eric, which is the same for all modes. The only difference is the way the headers are obtained. The old modes obtain them as before in order to address concerns about speed, but the 2 new ones use skb_flow_dissect. The unification of the hash function allows to remove a pointer from struct bonding and also a few extra functions that dealt with it. Two new functions are added which take care of the hashing based on bond->params.xmit_policy only: bond_xmit_hash() - global function, used by XOR and 3ad modes bond_flow_dissect() - used by bond_xmit_hash() to obtain the necessary headers and combine them according to bond->params.xmit_policy. Also factor out the ports extraction from skb_flow_dissect and add a new function - skb_flow_get_ports() which can be re-used. v2: add the flow_dissector patch and use skb_flow_get_ports in patch 02 v3: fix a bug in the flow_dissector patch that caused a different thoff by modifying the thoff argument in skb_flow_get_ports directly, most of the users already do it anyway. Also add the necessary export symbol for skb_flow_get_ports. v4: integrate the thoff bug fix in patch 01 v5: disintegrate the thoff bug fix and re-base on top of Eric's fix ==================== Signed-off-by: David S.

2013-10-03bonding: modify the old and add new xmit hash policiesNikolay Aleksandrov
This patch adds two new hash policy modes which use skb_flow_dissect: 3 - Encapsulated layer 2+3 4 - Encapsulated layer 3+4 There should be a good improvement for tunnel users in those modes. It also changes the old hash functions to: hash ^= (__force u32)flow.dst ^ (__force u32)flow.src; hash ^= (hash >> 16); hash ^= (hash >> 8); Where hash will be initialized either to L2 hash, that is SRCMAC[5] XOR DSTMAC[5], or to flow->ports which should be extracted from the upper layer. Flow's dst and src are also extracted based on the xmit policy either directly from the buffer or by using skb_flow_dissect, but in both cases if the protocol is IPv6 then dst and src are obtained by ipv6_addr_hash() on the real addresses. In case of a non-dissectable packet, the algorithms fall back to L2 hashing. The bond_set_mode_ops() function is now obsolete and thus deleted because it was used only to set the proper hash policy. Also we trim a pointer from struct bonding because we no longer need to keep the hash function, now there's only a single hash function - bond_xmit_hash that works based on bond->params.xmit_policy. The hash function and skb_flow_dissect were suggested by Eric Dumazet. The layer names were suggested by Andy Gospodarek, because I suck at semantics.
